If you like to install a Raspberry without a screen attached, then you will be happy for leveraging on this HowTo. It basically allows you to login to your Raspberry remotely after you have leveraged on the Raspberry Pi Imager to write the Raspberry Pi OS on the SD Card.
How To Setup Raspberry 3B For Headless SSH Access
Step 1 – Setup
First of all, download and install the Raspberry Pi Imager that allows to write the Raspberry Pi OS onto your preferred SD card. Please ensure this SD card is empty or the data that you have on this SD card is not needed anymore.
Step 2 – Enable SSH
Once installed, start the Raspberry Pi Imager and select your preferred operating system, e.g. Raspberry Pi OS. Secondly, select the SD card on which you like to write the Raspberry Pi OS. Before you click “WRITE” you select the Raspberry Pi Imager Settings, as of the below picture.
Raspberry Pi Imager Settings
If you are on a Mac computer, the computer most likely asks you whether you like to leverage on the WiFi settings of your Mac that are stored in the keychain. This makes the WiFi configuration very comfortable! You simply say yes, if the Raspberry will belong to the same WiFi than your Mac. If not, say no.
Pre-Fill WiFi from Keychain
Now, and this is important, we will be configuring in the Setting SSH by simply
- Click Enable SSH (as in the below picture)
- Use either password authentication of if you have a key, you better leverage on public-key authentication. On your Mac you can find your public key in your home-directory in the hidden subdirectory called .ssh

Finally, if you have not leveraged on the Mac Keychain and if you not on a Mac computer, you can pre-configure the WiFi network to which the Raspberry will belong to. In case you do not like to leverage on WiFi but on LAN only, then you do not configure this option.
Enable WiFi Configuration with Raspberry Imager
“Save” the configurations made. You will be leaving the Settings menu and you will be back on the main Raspberry Pi Imager menu. Click “WRITE”. NOTE: Writing the Raspberry Pi OS to the SD Card will DELETE all your data on the SD card. Make a backup before writing the SD card!

Step 3 – Find IP Address
Find out the IP Address of your Raspberry Pi. To do so, plug the SD card into the Raspberry Pi and try via your internet router to find out the IP address that was attached to your Raspberry Pi. I suggest to have a view of the IP addresses that your router provided to the devices in the network before you switch on the Raspberry Pi and then you compare after you switched on the Raspberry Pi. You would like to do this step via LAN cable, hence plug the Raspberry directly via LAN cable into the router.
In this example, the router attached the IP address of: 192.168.176.150
Step 4 – Connect by SSH
Since you know now the IP address, you are ready to go! I suggest for connecting via SSH to the Raspberry, you leverage for Windows on Putty, whilst you simply use the standard Terminal on a Mac or Linux system.
For connecting with a Mac or Linux terminal simply typ:
ssh pi@<IP ADDRESS OF YOUR RASPBERRY>
An example could be: ssh pi@192.168.176.150
Username Password:
- Since the Raspberry is newly setup, the default username is “pi” and the default password is “raspberry”. NOTE: You should change the password after first login!
- For Mac and Linux and since you used to login “ssh pi@<IP Address of your Raspberry” you only need to type the password
- For Windows you will need to enter both, username and password
- If you have in Step 2 selected key authentication, than you will most likely not need to type a password
You will observe a screen similar to the below, but of course with your IP addresses and your hostnames. One point, during the first login you will be asked to accept the new fingerprint that was detected. Respond with “Y” for yes. You can change the keys any time at a later stage.
mike@Mikes-Mac ~ % ssh pi@192.168.176.150 The authenticity of host '192.168.176.150 (192.168.176.150)' can't be established. ED25519 key fingerprint is SHA256:xkNXXXXXXXXXXwFJfJ/SV6ZhlnfaxfGIIXXXXXXXXXX. This host key is known by the following other names/addresses: ~/.ssh/known_hosts:6: 192.168.176.222 Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added '192.168.176.150' (ED25519) to the list of known hosts. pi@192.168.176.150's password: Linux raspberrypi 5.15.61-v7+ #1579 SMP Fri Aug 26 11:10:59 BST 2022 armv7l The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Here you go!
